>Number: 4628 >Category: kern >Synopsis: Device driver de won't accept "media" parameters to go Full Duplex:FDIV071 >Confidential: no >Severity: serious >Priority: high >Responsible: freebsd-bugs >State: open >Class: sw-bug >Submitter-Id: current-users >Arrival-Date: Thu Sep 25 12:10:01 PDT 1997 >Last-Modified: >Originator: Frank Durda IV >Organization: None >Release: FreeBSD 2.2-970921-RELENG i386 >Environment: 2.2-970921-RELENG system. >Description: On a system that has been running a 0618 snap using the DE driver in full duplex mode (by downloading the newer drivers directly from 3AM software), I find that using these drivers with the 970921 kernel will no longer allow you to select full-duplex mode using the -link0 link1 -link2 parameters in ifconfig. This appears to be because the 3AM drivers detect the presence of the new if_media mechanisms in the 970921 kernel. I then reverted to a completely stock 970921 setup (abandoning the add-on DE driver), and changed rc.conf (small problem here since ifconfig media command is documented as expecting parms in double quotes and the ifconfig line in rc.conf is already in double quotes), and the setting was rejected with the error: ifconfig: SIOCGIFMEDIA: Invalid argument The argument I am trying to pass is "Full Duplex 10baseT", exactly as it appears in the 970921 pci/if_de.c module. (The board in use is a PCI adapter.) So I tried the other choices listed in the DE driver and all return the same error message, even when entered from the command line: ifconfig de0 media "Full Duplex 10baseT" ifconfig: SIOCGIFMEDIA: Invalid argument ifconfig de0 media "10baseT" ifconfig: SIOCGIFMEDIA: Invalid argument I can't tell that this "media" command works at all. Note that because the choices for the "media" command are not documented in the man 4 de page, the source code was the only place to obtain what appears to be the valid choices. Because we could not get around this problem and must use full duplex, we were forced to go back to the 0618 kernel we had been using previously with the 3AM driver and are happily doing full duplex again. The reason we tried to go with the newer kernel was to try to get relief from the SCSI "timed-out while idle errors", but even the 970921 kernel still produces these (although the volume is reduced). The SCSI problems will be the subject of another problem report. >How-To-Repeat: With a DE card (2.3 or 2.4 step) installed, attempt to set the card into Full duplex mode using the ifconfig media command. You must look in the source code since the parameters are not documented. >Fix: Apart from going back to pre-"if_media" driver code, unknown. >Audit-Trail: >Unformatted:
